ADJUSTABLE (EASTER.

Specification of Letters Patent.

Patented April 21, 1908.

Application filed November 5:10, 1907. Serial No. 404,608.

To all whom it may concern:

Be it known that I, ERNEST DEVINE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Adjustable Casters; and I do hereby declare the following to be afull, clear, and exact descri tion of the invention,

such as will enable ot ers skilled in the art to which it appertains to make and use the same.

My invention relates to new and useful improvements in means for attaching casters to stoves, furniture, or similar articles adapted to be moved from place to place and my object is to provide means for adjusting the casters, whereby the articles may rest upon their supporting legs, .or upon the casters direct.

Other objects and advantages willbe hereinafter referred to and more particularly pointed out in the claims.

In the accom anying drawings which are made a part of t us application, Figure 1 is a perspective view of one corner of a stove base, showing a caster secured thereto. Fig. 2 is a sectional view through the base and supporting leg therefor, showing the manner of mounting and adjusting the caster, and, Fig. 3 is a plan view of a wrench employed for operating the caster adjusting mechanism.

Referring to the drawings in which similar reference numerals designate corresponding parts throughout the several views, 1 indicates a base which, inthis instance, represents the base of a stove, to the corners of which are secured in any preferred manner, supporting legs 2. The lower ends of the legs 2 are preferably provided with a recess 3 formed by cutting away the inner, lower edge of the leg, or providing the leg with a curved art 4, said terminal being adapted to norma y rest upon the floor or other .suitable point and support the base.

When it is desired to move the article from place to place, I provide the usual or any preferred form of caster 5, which caster is provided with a stem 6, said stem extending vertically through a socket 7, in that portion of the leg above the recess.

The socket 3, adjacent its upper end, is

provided with .threads 8 to receive the threaded end 9 of an adjusting bolt 10, said adjusting bolt being introduced into the enlarged u per end of the socket 7 and the unthreade portoin 11 thereof being provided with square faces, with which is adapted to engage the bifurcated end 12 of a wrench 13,

and by which means the bolt is adjusted longitudinally in the upper end of the socket.

In order to readily apply the wrench to the squared portion of the bolt '10, the leg 2 is provided with a slot 14, which is disposed horizontally in the upper end of the leg 2, and extends inwardly from one face of the leg and intersects the socket 7 at a point above the threads in the socket, whereb when the wrench is introduced into the s ot, the squared portion of the bolt 10 will be en- .gaged and the-slot is of sufiicient length to allow the wrench to readily swing laterally to rotate the bolt.

In adjusting the caster downwardly, when it is desired to move the object to which it is attached, the wrench 1 3 is applied and the bolt .10 turned downwardly in the threaded portion of the socket 7, which will result in lowering the caster and elevating the lower end of the leg out of engagement with the object on which it is resting, the wei ht of the article then bein supported by t e caster and, as the stem 18 swivelly mounted in the socket 7, the article can be moved to any suitable point and when properly located, the wrench is again applied and the bolt 10 moved u wardly in the socket, whereupon 'the artic e to which the caster is attached,

will descend and again rest upon its supporting legs.

t will thus be seen that I have provided a very cheap and economical means for adjustably securing a caster to the legs of a stoveor other objects and further that the caster may be readily extended to support the weight of the stove and, while I have shown a particular form of su porting leg for receiving the caster, it wil be readily understood that any suitable form of leg may be employed havin a solid upper end in which to form the soc et for the reception of the stem and it will likewise be seen that with such changes as clearly fall within the scope ably attaching a caster to an object, comprising the combination with a supporting leg having a vertically disposed socket therein, of a caster, a stem on said caster adapted to enter said socket and adjustable means above the end of said stem engaging the wall of said socket and resting on the end of said stem adapted to elevate the supporting leg and dispose the Weight on the caster.

2. The herein described means for adjustably securin a caster to an object, comprising the com ination With a supporting leg having a vertically disposed socket therethrough, threads adjacent the up er end of said socket, said supporting leg a 0 having a slot intersecting said socket adjacent its upper end, said slot being flared, of a caster, a stem on said caster adapted to enter said socket, a bolt in the upper end of said socket and above the stem adapted to direct pressure on the up er end of said stem, threads on said bolt a apted to engage the threads in the socket and means to rotate said bolt whereby the supporting leg will be raised or lowered.

3. The herein described means for adjustably attaching a caster to an object, cornprising the combination with a supporting bolt in the upper end of said socket, threads on the lower portion of said bolt adapted to engage the threads in the socket, the remaining portion of said bolt being squared and a wrench adapted to extend through the slot and engage the squared portion of the bolt,

whereby, when the wrench is swung laterally, the bolt will be turned and the supporting le raised or lowered on said stein.

in testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
